Using the Flow Graph Debugger, you can add breakpoints to any input or output port
of a node. Once a node port is triggered, the game is paused and the Flow Graph Editor
displays the applicable node in the center of the graph pane.

To resume the game once a breakpoint is triggered, click the play (Start Flowgraph
Update) toolbar icon, or press F5.

To manage Flow Graph breakpoints

In Flow Graph Editor, right-click the applicable input or output node port, then do
the following as needed:

To create a breakpoint, click Add Breakpoint. A red dot is displayed next to the node port.

To remove a breakpoint, click Remove Breakpoint.

To enable or disable a breakpoint, toggle the Enabled check box.

To remove all breakpoints on a node, or for all nodes on the entire flow graph, click
Remove Breakpoints for Node or Remove Breakpoints for Graph respectively.

Every breakpoint can be converted to a tracepoint, which instead of pausing the game
outputs the information about a triggered breakpoint to the console and to a log file.
Simply right-click on the applicable breakpoint-enabled node port, then click Tracepoint.. The red dot changes to a red diamond to indicate that the port has a tracepoint
enabled on it.
